"Ghiyath ud-din Baysunghur, commonly known as Baysonqor or Baysongor, Baysonghor or (incorrectly) as Baysunqar, also called Sultan Bāysonḡor Bahādor Khan (1397 - 1433) was a prince from the house of Timurids. He was known as a patron of arts and architecture, the leading patron of the Persian miniature in Persia, commissioning the Baysonghor Shahnameh and other works, as well as being a prominent calligrapher.
Baysunghur was a son of Shah Rukh, the ruler of Persia and Transoxania, and Shah Rukh's most prominent wife Gawhar Shad.
In the view of modern historians, Baysunghur was actually a better statesman than his more famous elder brother, Ulugh Beg, who inherited Shah Rukh's throne, but who "must have envied his younger brother, Baisunghur, whom his father never saddled with major responsibilities, which left him free to build his elegant madrasas in Herat, gather his ancient books, assemble his artists, and drink"." - (en.wikipedia.org 11.08.2021)
